1 GENERAL SAFETY INFORMATION
The information that follows, together with local site regulations, must be studied by
personnel concerned with the operation or maintenance of the equipment, to ensure
awareness of potential hazards.
WARNING- RF Power Hazard: High levels of RF power are present in the unit. Exposure to
RF or microwave power can cause burns and may be harmful to your health.
Turn off power supplies before removing covers or disconnecting any RF cables, and before
inspecting damaged cables or antennas.
Avoid standing in front of high gain antennas (such as a dish) and never look into the open
end of a waveguide or cable where RF power may be present.
Users are strongly recommended to return any equipment that requires RF servicing to RF
Central.
WARNING- GaAs / BeO Hazard: Certain components inside the equipment contain Gallium
Arsenide and Beryllium Oxide that are toxic substances. While safe to handle under normal
circumstances, individual components must not be cut, broken apart, incinerated or
chemically processed. In the case of Beryllium Oxide, a white ceramic material, the principal
hazard is from the dust or fumes which are carcinogenic if ingested, inhaled or entering
damaged skin.
Please consult your local authority before disposing of these components.
CAUTION- Tantalum Capacitors: When subjected to reverse or excess forward voltage,
ripple current or temperature these components may rupture and could potentially cause
personal injury.
CAUTION: This system contains MOS devices. Electro-Static Discharge (ESD) precautions
should be employed to prevent accidental damage.

1.1 Health & Safety
Exposure to Non Ionizing (RF) Radiation/Safe Working Dista nc es
The safe working distance from a transmitting antenna may be calculated from the relationship:
PT. GR.w
D =
√
In which D = safe working distance (meters)
PT = transmitter or combiner power output (watts)
GR = antenna gain ratio = anti log (gain dBi ÷10)
w = Maximum allowed power density (watts/square meter)
The RF power density value is determined by reference to safety guidelines for exposure of the
human body to non-ionizing radiation. It is important to note that the guidelines adopted differ
throughout the world and are from time-to-time re-issued with revised guidelines. For RF Central
use, a maximum power density limit (w) of 1w/m² is to be applied when calculating minimum safe
working distances. Refer to Appendix A.
Important Note: It must be remembered that any transmitting equipment radiating power at
frequencies of 100 kHz and higher, has the potential to produce thermal and athermal effects
upon the human body.
To be safe:
a) Operators should not stand or walk in front of any antenna, nor should they allow
b) Operators should not operate any RF transmitter or power amplifier with any of its

1.2 Maximum RF Power Density Limits
The RF Radiation Power Density limit figure recommended by RF Central is based upon
guideline levels published in:
a. IEEE standard C95.1 1999 - IEEE Standard for Safety Levels with respect to Human
Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.
b. Guidelines for Limiting Exposure to Time-varying Electric, Magnetic & Electromagnetic
Fields (up to 300 GHz) published in 1998 by the Secretariat of the International Commission
on Non-Ionizing Radiation Protection (ICNIRP).
Both documents define guideline RF power density limits for "Controlled" and "Uncontrolled"
environments. An uncontrolled environment is defined as one in which the person subjected
to the RF radiation may be unaware of and has no control over the radiation energy received.
The uncontrolled environment conditions can arise, even in the best regulated operations,
and, for this reason, the limits defined for the uncontrolled environment have been assumed
for the RF Central recommended limit.
Documents a) and b) also show the RF power density guidelines to be frequency dependent.
Different power density / frequency characteristics are presented in the two documents. To
avoid complexity and to avoid areas of uncertainty, RF Central recommends the use of a
single power density limit across the frequency range 100 kHz to 300 GHz. The 1w/m² power
density limit we recommend satisfies the most stringent of the guidelines published to date.

7.1 Audio / Video Encoder
The Encoder board consists of the following main functions:
• SDI to Digital de-serializer. Converts the SMPTE-259M-C serial digital video input
to an 8 bit parallel digital video bus.
• Analog to Digital Video Converter, 10 bit over sampling ADC
Takes either composite video (75 , 1v p-p) (CVBS); YC or YUV inputs in either
PAL / NTSC format and converts to an 8 bit parallel digital video bus.
• FPGA selects the required 8 bit parallel digital video bus from either the SDI or
analog input, packets this data for input to the MPEG2 encoder. A relay is used to
route the input from the BNC (either SDI or CVBS) to either the SDI de-serializer or
the PAL/NTSC decoder.

Operator’s Manual RF ExtremeCare: 866.732.0113
• Audio Analog to Digital Converter, 48 kHz, 24 bit. Four high impedance analog
inputs. The channels are first buffered by a variable gain stage to cater for either
Mic or Line level inputs. A switchable 20 dB stage is also included to cater for low
level Mic inputs. The audio channels are then converted into digital signals and
passed to the MPEG2 Encoder.
• Audio SDI de-embedder. Extracts digital audio from the SDI stream
• MPEG2 Encoder. Compresses the video and audio. The encoder uses a suite of
MPEG2 compliant compression techniques, where the data bit rate is reduced by
processing over multiple picture frames. The absolute picture (Intra frame) is
interleaved with pictures that are created using difference data (Predicted frame)
with Bi-directionally predicted frames (4:2:2 Only) in conjunction with motion
compensation; thus low data rates down to 4 Mbps, can be achieved.
The encoder includes special modes which are optimized for low delay (latency).
The encoding parameters are loaded into the encoder at power up. These are
selected from one of the ‘preset’ encoder memories. See 8.4.6 and Appendix B
• ASI routing.
As an alternative to the internal MPEG encoder an external ASI data stream may
be used. The ASI input to the front panel is converted to parallel and automatically
selected for 188 / 204 / byte mode inputs, the signal is then configured for the
modulator input format and routed direct to the transport stream output, bypassing
the MPEG2 coder.
• DC Power Supplies
Switching DC / DC converters are used to generate the various supplies from the
incoming 9-18V battery supply. These include 2.5, 3.3V, 5V, 8V and +/-5V
supplies.
There are no field replaceable parts on the Encoder board. If a fault occurs with the board,
please contact RF Central for technical assistance.

Operator’s Manual RF ExtremeCare: 866.732.0113
7.2 COFDM Modulator
The normal scheme of COFDM modulation adopted by RF Central for the RMT-II Dual Band
is 2k carriers with selection of 6, 7, 8 MHz RF bandwidth.
The COFDM modulator has been designed to take its input from the MPEG2 encoder, or from
an external ASI. This transport stream is then modulated directly to the output frequency band
(e.g. 2 GHz). This method reduces the occurrence of inter-modulated harmonic frequencies
and requires less up-conversion.
The COFDM modulator RF output is via the SMB connector. This output is then fed, via the
analog/digital RF switch, into the power amplifier. The nominal RF output level from the
Modulator is –9 dBm.
When the traffic being carried by the Tx is video and audio, the modulator is automatically
configured to match the data rate of the MPEG2 Encoder as defined by the selected
parameter set.
When the traffic being carried by the Tx is ASI, the modulator may be set for modulation,
FEC, and guard interval, according to the chart in Appendix B
There are no field replaceable parts on the COFDM modulator. If a fault occurs with the
board please contact RF Central for technical assistance.
7.3 Power Amplifier
The function of the power amplifier is to amplify the signal from the COFDM modulator to a
suitable level for transmission. The amplifier is required to be highly linear to accommodate
the high order modulation modes employed for digital system operation, with very low
distortion (low inter-modulation between carriers). The nominal output power is +27dBm
(500mW) (band specific).
The status of the PA is shown by LED mentioned in clause 8.2, and also displayed in the
status menu.
To ensure good RF practice, when power is applied to the RMT-II Dual Band, always make
sure that there is a suitable load or antenna connected to the RF output.
There are no field replaceable parts in the power amplifier. If a fault occurs with this module
please contact RF Central for technical assistance.

C two-wire interface is used to
communicate with all other intelligent devices within the unit. This carries the command data
and reads back status data from all boards within the unit.
All configuration parameters, video settings, audio settings, MPEG encoder parameters,
frequencies etc; are held on this board. This allows the ability to change other boards within
the unit without the loss of set-up parameters.
At power-up, this board initializes all the other boards and during normal operation monitors
all the major functions and reports any problems as part of the unit status.
Operator control of the set-up parameters is via the 6 push buttons on the front of the
transmitter control unit. The graphic LCD display is connected directly to the board and is also
provided with LED back-lighting under the control of the controller.

8 CONFIGURING THE TRANSMITTER
8.1 Control Mode
The RMT-II Dual Band has 3 possible control modes
• “Switches” selection of channel frequency and PA On/Off is selected via the two frontpanel rocker switches. In this mode control is restricted to these two functions.
• “Keypad” Control via the 6 push buttons in conjunction with the menu tree
• “Remote” via RS232/RS485 remote control data interface.
Additionally, when in Local control, Band selection may be either from the front panel push
button, or from the rear panel “Aux” connector. When using the Aux connector, switching is
made by applying a +ve voltage to the D type to select the 7 GHz Band. Absence of this
voltage selects the 2 GHz band. See paragraph 6.1.8

The Receiving Equipment
The RMT-II Dual Band transmitter may be used with a variety of RF Central digital receivers
including
RFX-RMR-II 2 GHz rack-mounted receiver
RFX-RMR-II 2 / 7 GHz Dual Band rack-mounted receiver
PMR-II portable receiver
RMR-X6 / RMR-X6-ll Diversity Receiver
Full details of the operation of the receivers are given in the associated manuals
When used with the RMT-II Dual Band transmitter, the RMR-ll, RMR-II Dual Band, PMR-II,
RMR-X6, X6-ll digital receiving equipment produces four audio channels (analog and AES3
digital) together with SDI and composite video outputs. These receivers also have an ASI
output.
Check that audio, video, and DC cables of sufficient total length and are in good condition. If
extension cables are necessary ensure that the connectors are compatible and of good quality
to avoid problems at site.
Check that the receiving antenna / receiver interfaces are clean and free from dust and other
unwanted materials.
If tripods are to be used to mount the equipment, make sure that some means of securing the
tripod or of weighting it down is provided. Gusty wind conditions may put installations at risk,
particularly when parabolic antenna dishes are to be used.
Check that the receiver channel frequencies are compatible with those of the RMT-II Dual
Band Transmitter and set the channel selector switch to the channel number required. The
receiver is labeled with channel number and frequency information.
9.3 Transmitter / Receiver tests
Whenever practical, set up the system and test it before leaving for the remote site to
ensure that all components of the system are working properly. Checking the system,
making necessary adjustments, and taking corrective actions ahead of time, will pay off
later when setting up at the remote site.
